Before we're even born, our bodies begin to grow and train an army of spies and assassins, creating a crew of immune system fighters in the upper chest's thymus gland. While this production is dominated by T cells, other immune cells such as B cells and plasma cells can be generated within the thymus, albeit at a very low level. After adolescence, the thymus reduces production at its 'spy and assassin' factory to a trickle. This has consequences because as we age, our immune system makes mistakes, leading to mutations in our DNA; changes in the types of antibodies we produce, and odd feedback loops. Those glitches contribute to the generation of chronic lymphocytic leukemia or B-cell lymphomas such as non-Hodgkin lymphoma. They can also contribute to the development of autoimmune diseases such as lupus and myasthenia gravis. "We think this all has to do with a life-or-death signalling loop," said Dr. Peter Pioli, who moved to the University of Saskatchewan last year to become an assistant professor of Biochemistry, Microbiology & Immunology. In February, he published his findings in iScience. "For autoimmune patients, you get this thymus that gets filled up with all these B-cells and plasma cells, so you no longer have this little trickle; you have a bit of a runaway train," he said. Using mouse models, Pioli and his team are trying to piece together the triggers convincing aging B-cells to mistakenly ramp up plasma cell production. They want to know how this impacts the development of various diseases. In this episode, Pioli explains his interest in plasma cells. "It fascinates and confounds you all in one," said Pioli. "This one cell has to have this perfectly aligned machinery to do this. And it's kind of hard to look away when you find something like that." A "curious troublemaker" who loved to tinker as a kid, Pioli remembers taking apart tools and objects in his parents' garage, removing pieces and trying to rebuild them. That curiosity carried him through his undergraduate, graduate studies and post-doctoral work in Wisconsin, Utah, and California. "It's just a lot of fun," said Pioli. "You get the payoff of hopefully finding something that could actually help someone someday: understanding aging, understanding these breakdowns that lead to autoimmune diseases and tissue breakdown." Pioli admits his scientific career has taken plenty of detours, but he's extremely grateful it unfolded the way it did. "There's a lot you learn from that, not just in terms of experience," he said. "You also learn about yourself in terms of your potential to persevere. And maybe the potential to be supremely stubborn, to keep at it."

M., Leong, E., Shen, Z., Goh, W., Kratina, T., Rautela, J., Vince, J., Nicholson, S., Huntington, N. Abstract: The clinical development of Natural Killer (NK) cell-mediated immunotherapy marks a milestone in the development of new cancer therapies and has gained traction due to the intrinsic ability of the NK cell to target and kill tumour cells. To fully harness the tumour killing ability of NK cells, we need to improve NK cell persistence and overcome suppression of NK cell activation in the tumour microenvironment. The trans-membrane, protein tyrosine phosphatase CD45, regulates NK cell homeostasis, with genetic loss of CD45 in mice resulting in increased numbers of mature NK cells [1-3]. This suggests that CD45-deficient NK cells might display enhanced persistence following adoptive transfer. However, here we demonstrated that adoptive transfer of CD45-deficiency did not enhance NK cell persistence in mice, and instead, the homeostatic disturbance of NK cells in CD45-deficient mice stemmed from a developmental defect in the common lymphoid progenitor population. The enhanced maturation within the CD45-deficient NK cell compartment was intrinsic to the NK cell lineage, and independent of the developmental defect. CD45 is not a conventional immune checkpoint candidate, as systemic loss is detrimental to T and B cell development [4-6], compromising the adaptive immune system. Nonetheless, this study suggests that inhibition of CD45 in progenitor or stem cell populations may improve the yield of in vitro generated NK cells for adoptive therapy.

C., Vainchtein, I. D., Escoubas, C. C., Molofsky, A. B., Molofsky, A. V. Abstract: The innate immune system plays essential roles in brain synaptic development, and immune dysregulation is implicated in neurodevelopmental diseases. Here we show that a subset of innate lymphocytes (group 2 innate lymphoid cells, ILC2s) is required for cortical inhibitory synapse maturation and adult social behavior. ILC2s expanded in the developing meninges and produced a surge of their canonical cytokine Interleukin-13 (IL-13) between postnatal days 5-15. Loss of ILC2s decreased cortical inhibitory synapse numbers in the postnatal period where as ILC2 transplant was sufficient to increase inhibitory synapse numbers. Deletion of the IL-4/IL-13 receptor (Il4ra) from inhibitory neurons phenocopied the reduction inhibitory synapses. Both ILC2 deficient and neuronal Il4ra deficient animals had similar and selective impairments in adult social behavior. These data define a type 2 immune circuit in early life that shapes adult brain function. Copy rights belong to original authors. Visit the link for more info Podcast created by Paper Player, LLC

ILC3 can contribute to the progression and aggravation of IBD's while both IL-22 and IL-17, along with IFN-γ, are overexpressed by the dysregulation of NCR− ILC3 or NCR+ ILC3 function NCR (natural cytotoxicity receptors), are type 1 transmembrane proteins of the immunoglobulin superfamily. Upon stimulation, NCR's mediate NK killing and release of IFNγ. They bind viral ligands such as hemagglutinins, neuraminidases, bacterial ligands, and cellular ligands related with auto immune diseases, tumour growth, and associated aging morbidity.

Chronic stress can literally destroy your immune system. Cortisol is activated by stress. Lymphoid tissue is an area where you have a lot of immune reactions to keep pathogens away from different organs. High cortisol will divert amino acids from the lymphoid tissue, basically shrinking this tissue. It makes your immune system smaller. Antibodies are produced by the immune system, and they help develop immunity. They don't necessarily kill pathogens, but they put a tag on them for other immune cells to kill them. If you have enough antibodies in your system, you are protected. But, with high cortisol, you can have a decrease in overall antibody production. You also have various barriers of immune defense. But, high cortisol can create a break down in your cellular barriers, which can raise your susceptibility to viral and bacterial infections. Keeping your immune system strong isn't just about good nutrition; it's also about keeping your stress as low as possible.

Some cancers come for dogs right away, and others take longer. Chronic Lymphocytic Leukemia (CLL) can be hard to diagnose, because it often develops while the dog acts totally healthy. But routine blood tests can tip a veterinarian off that something is wrong … and when you know early there are lots of things you can do to help your dog. Today James Jacobson takes a question about CLL, also known as Lymphoid Leukemia, from Delisa in Alabama, and asks Dr. Dressler for an answer. Dr. Demian Dressler is co-author of our podcast sponsor, the book The Dog Cancer Survival Guide: Full Spectrum Treatments to Optimize Your Dog’s Life Quality and Longevity. Links Mentioned in Today’s Show: The Dog Cancer Survival Guide: Full Spectrum Treatments to Optimize Your Dog’s Life Quality and Longevity. Apocaps can be found in many veterinary offices and online, including at https://Apocaps.comK9 Immunity can be found in many places online, including at https://www.k9medicinals.comDelisa is a member of the private Facebook group for readers of Dr. Dressler’s book “The Dog Cancer Survival Guide” https://www.facebook.com/groups/dogcancersupport/ Here’s a good article on lymphoid leukemia or lymphocytic leukemia on the National Canine Cancer Foundation’s website: https://wearethecure.org/learn-more-about-canine-cancer/canine-cancer-library/lymphoid-leukemia/Here’s a good article that will help you to understand the difference among blood cancers, including chronic lymphocytic leukemia: https://www.vetfolio.com/learn/article/lymphoid-leukemia-in-dogsYou can reach out to Dr. Demian Dressler directly on his veterinary hospital’s website: https://VetinKihei.com. Quick Overview of CLL from James Jacobson’s conversation with Dr. Nancy Reese:First, let’s get clarity on this disease a little, because it’s often confused with a much more common dog cancer called lymphoma. To find out more, I asked one of our Full Spectrum veterinarians, Dr. Nancy Reese about Chronic Lymphocytic Leukemia, also known as Chronic Lymphoid Leukemia, or CLL for short. I don’t have tape of our conversation about CLL, but you’ll hear from Dr. Nancy in an upcoming episode about Covid-19.By email, Dr. Nancy explained that lymphoma and lymphocytic leukemia are both cancers of the lymphocytes. What’s a lymphocyte? It’s a type of white blood cell that is born in the bone marrow, and less often, the spleen. Those white blood cells circulate in the blood stream and the lymph system, fighting infections in cells all over the body. So, when lymphocytes get cancer, you’ve got a systemic disease, which means the cancer is everywhere by definition. In lymphoma, the cancerous lymphocytes tend to collect in the lymph glands, which tend to get swollen. In lymphocytic leukemia, the cancerous lymphocytes tend to circulate in the bloodstream. Same cells, different locations in the body. Either way, the cancer cells, the lymphoid or lymphocytic cells, are everywhere ... so when you get this diagnosis, the veterinarian will almost always recommend chemotherapy. That's the only conventional treatment that circulates in the blood and goes everywhere in the body, right?So today’s question is this: when do you need to start the chemo for Lymphoid or Lymphocytic Leukemia? Right when you get the diagnosis? Or can you wait a while?Well, the answer depends on whether the lymphocytic leukemia is acute or chronic!Chronic conditions are long-developing, as opposed to severe and sudden, or acute conditions. Right? So Chronic Lymphocytic Leukemia is a long-developing cancer of lymphocytes. Also, Dr. Nancy added, the lymphocytes involved in CLL are mature and divide slowly, at the same rate as a normal cell. So that’s one reason this form of the cancer takes a long time to develop.There is an acute form of lymphocytic leukemia, as well, that is much more immediately dangerous, and it develops in a immature form of the lymphocyte cells, a form that rapidly divides. So the Acute Lymphocytic Leukemia, or ALL, divides very fast, comes on suddenly, and rapidly progresses.We’ll hear more from Dr. Nancy directly in an upcoming episode about coronavirus and dogs that is literally a must-listen. She’s the perfect person to ask about the pandemic we’re in right now, because she is not only a veterinarian with thirty years of experience under her belt, she’s also got a Ph.D. in Epidemiology.About Today’s Guest, Dr. Demian Dressler: Dr. Demian Dressler, DVM is internationally recognized as “the dog cancer vet” because of his innovations in the field of dog cancer management.

Dr Aaron Logan speaks with ecancertv at AACR 2016 about developments in determining the levels of residual disease presence in patients following treatment. He reports that, utilising the molecular techniques becoming available, detecting the signs of a patient's deep disease response are an effective predictor of disease free survival. With novel technologies becoming standardised techniques, the ability to determine a patients cancer clonotype and search for its remission in greater detail than light microscopy alone may make it possible to improve screening, therapy, and response duration.

Lymphoid and non-lymphoid tissues accommodate defined numbers of dendritic cells (DCs). There, DC-life span is influenced by various components such as proliferation and cell division triggered by cytokines, maturation processes in response to extracellular inflammatory and microbial substances, as well as induction of migration and apoptosis. Previous work has demonstrated the importance of specific numbers of DCs in tissues, as changes of DC numbers or DC life span could alter immunity, tolerance or inflammation resulting in various immune diseases. However, currently it is still unknown how DC life span and homeostasis is regulated in vivo. RhoA is a member of Rho GTPase-family, which plays important roles in regulating cytoskeleton organization, proliferation, migration and survival. However, our current knowledge about RhoA-functions is based mostly on studies using dominant negative and constitutively active RhoA-mutants, which have possible unspecific effects on other members of the Rho GTPase family. Therefore, we used a LoxP/Cre recombinase approach to knock out RhoA selectively in DCs. Here we found that GTPase RhoA controlled the homeostasis of mature DCs, and deletion of RhoA caused significantly reduced numbers of CD8+CD11b- and CD11b+Esamhi DC subsets, while CD11b+Esamlo DCs remained largely unaltered. Loss of RhoA interfered with homeostatic proliferation, cytokinesis, survival and turnover of cDCs. By performing proteomic analysis, we found that a pro-survival PI3Kγ/Akt/BAD pathway was deregulated in RhoA-ko DCs. Taken together, our findings indicate that RhoA plays a critical role in regulating DC-homeostasis, deletion of which decreases DC numbers resulting in impaired immune protection.
Tanya M. Wildes, MD, MSCI, Washington University School of Medicine, discusses the treatment options for lymphoid malignancies in the older patient.
Dr Strasser talks to ecancertv at ASH 2013. Impaired apoptosis is considered one of the prerequisites for the development of most, if not all, cancers, but the mechanisms that guarantee the sustained survival of most cancer cells remain unknown. Members of the Bcl-2 family are key regulators of apoptosis and include proteins essential for cell survival and those required to initiate cell death. Studies with transgenic mice have shown that over-expression of Bcl-2 or related pro-survival family proteins, such as Bcl-xL or Mcl-1, can promote tumorigenesis, particularly in conjunction with mutations that deregulate cell cycle control, such as deregulated c-myc expression. It is, however, not known whether expression of pro-survival Bcl-2 family members under endogenous control is required to maintain the survival of cells undergoing neoplastic transformation. Using Eµ-myc transgenic mice, a well-characterized model of human Burkitt’s lymphoma, we investigated the role of endogenous Bcl-2 in lymphoma development. Bcl-2 was found to be dispensable for the development of Eµ-myc pre-B/B lymphoma. In contrast, loss of Bcl-xL and even, more remarkable, loss of a single allele of Mcl1 greatly impaired lymphoma development. Experiments with inducible knockout mice demonstrated that Mcl-1 but not Bcl-xL is essential for the sustained survival and expansion of Myc-driven malignant pore-B/B lymphoma. Remarkably, even loss of one Mcl1allele greatly impaired lymphoma growth. These findings were translated into using lymphoid malignancies by using inducible expression of selective antagonists of distinct pro-survival Bcl-2 family members. Such studies showed that Mcl-1 is also critical for the sustained survival and expansion of Burkitt Lymphoma, a Myc-driven malignancy. These observations indicate that (even relatively weak) targeting of Mcl-1 may be an attractive strategy.

The distribution of the functional subsets of porcine T cells, the cytolytic/suppressor (Tc/s) and the helper/inducer (Th/i) cells was studied in cryostat sections of thymus, lymph nodes, tonsils, Peyer's patches, spleen and liver using the indirect immunoperoxidase technique. Three murine monoclonal antibodies (mAb) were used. The mAb 8/1 reacts with an antigen present on all T cells and on cells of the myeloid lineage; the antigen has not yet been characterized biochemically. The mAb 295/33 (anti-T8) binds to the porcine T8 antigen and defines the Tc/s subset, while mAb PT-4 (anti-T4) detects the porcine T4 antigen and defines the Th/i subset. Practically all thymocytes were stained by mAb 8/1. The majority of cortical thymocytes apparently co-expressed T8 and T4, whereas distinct fractions of medullary cells were labelled by either anti-T8 or anti-T4. In peripheral lymphoid organs all three mAb reacted with cells in the thymus-dependent areas and with cells scattered in the lymphoid follicles. In lymph nodes, tonsils and Peyer's patches, anti-T8 and anti-T4 each labelled approximately half of the cells stained by mAb 8/1. In the periarteriolar lymphoid sheath of the spleen, anti-T4 labelled more cells than did anti-T8. The reactivity of mAb 8/1 with the Kupffer cells of the liver demonstrated the expression of the 8/1 antigen on cells of the monocyte lineage. The T8 and T4 antigens could not be detected in acetone-fixed and paraffin-embedded sections, while the antigen recognized by mAb 8/1 remained preserved. Altogether, despite an inverted microanatomical structure of porcine lymph nodes, the frequency and distribution of T8+ and T4+ cells in thymus-dependent areas proved to be similar to those found in other species.
